I disagree with the premise of this article. Just because miners are based in China is not proof of collusion. I agree there is some fishy stuff going on with Bitmain and Antpool and others, but isn't it in their best interest not to break faith?
Wouldn't exchanges (who are holding all the money and are not (explicitly NOT) based in China still have the cash to fund withdrawals? Wouldn't the rest of the world STILL be free to fork the chain to a good faith ecosystem? Isn't Bitcoin Core largely made up of non-Chinese?
